Is there an a/c out there that has four engines; 2 rear and 2 under-wing. So kind of like a MD80 with two additional engines under the wing. With this configuration, you could have a large wide-body and have a more distributed weight than with a 747.

How long until an a/c manufacturer make an a/c with this configuration?

Any comments are welcome.

There's nothing out there ... yet ... like you described. The VC-10 and Super VC-10 have four engines in the rear, as does the IL-62. The L1011, DC-10, and MD-11 have one engine in the rear and one engine under each wing. I don't really think you're going to see an airliner designed with the configuration you're talking about. As large as engines are getting, it's likely all four engine layouts will mount 2 engines under each wing.
